It is founcl inpractiee'thet contain I of plies' em loyed wil largely depend upon the size of the fiiii'shed" cO'ntQiiiefeii'd the u'setQ which it is to be" r ers of a size readily adapting them for use as butter tubs, or for. analogous purposes, may be constructed in the manner described, the plaits or folds C serving to impart to the container great rigidity and strength through the reinforcing thereof with the employment of an adhesive as described. The present invention is capable, however, of employment in the manufacturing of smaller or larger containers than butter tubs, and is particularlyapplicable for use in the manufacture of candy containers, paint cans, or other containers, where rigidity and durability, together with liquid impervious qualities are desirable.

In manner described, a strong, durable and rigid container may be manufactured in a simple, expeditious and economical manner, without the use of dies or machinery requiring nice adjustments. The present invention is thus a marked contrast with the prior practice employed in the manufacture of tapered paper containers and the finished container may be readily made far more serviceable and durable than die cut and formed containers and at but a fraction of the cost- As a result of the practicing of the method of this invention, as hereinbefore described, the resulting article is a container body to which may be applied any suitable bottom and top closure, the character of which will, of course, greatly depend upon the use to which the container is to be put. In practice, paper bottoms and tops may be applied to the bodies so constructed, or they may be supplied with wooden or metallic bottoms and tops as occasion may require. In view of the fact that-the application of a top or bottom to the container involves no part of the present invention, it has not been considered necessary to show and describe the manner in which they may be applied.

- In practice, the mandrel A will be made collapsible, but as this mandrel, per se, forms no part of the present invention, it has not been considered necessary to show. in detail the collapsible mandrel and the same has been shown solid for diagrammatic illustration.

In carrying out the present invention, the foregoing illustrative sequence of steps may be slightly varied without departing from the spirit of the invention In any event, the underlying principle of the invention remains the same, i. e., the linear dimension of at least one edge of the web is changed or varied by overlapping lateral portions of the paper web to bring about the contraction in the linear dimension. Eor these reasons, the present invention is not to be understood as limited to the specific showings made in the drawing, but is to be construed as is broadly novel as is commensurate with the appended claims.

compensating for the taper of the mandrel by providlng the web with transversely extending fiat tapered plaits to change the linear dimension of one edge thereof.

3. The method of making paper containers which consists in winding a. straight web of paper upon a tapered-mandrel, and compensating for the taper of the mandrel by providing the web with transversely extending fiat tapered plaits for a portion of its width to effect a change in the linear dimension of one edge thereof, while the linear dimension of the other edge of the web is maintained constant. Y

a. The method of making mult-i ply paper containers which consists in winding a straight web of paper on a tapered mandrel, forming tapering plaits in the web, which plaits extend from one and compensate drel, and so spacing the plaits from one another longitudinally of the web, that the suc cessive plaits of any one ply will lie intermediate the successive plaits of adjacent plies. I 5. The method of makingmulti ply paper containers which consists in winding a straight web of paper upon a tapered mandrel, providing the web with transversely extending tapered plaits .to compensate for the taper of the mandrel and employing the successive plies to maintain the plaits of each preceding ply folded down flat.

6. The method of making paper contain-- ers which consists in winding a straight strip of paper upon a tapered mandrel, compen eating for the taper of the mandrel by forming tapered transversely extending plaits in the web, and folding said plaits down flat.

7 The method of making tapered paper containers which consists in wrapping a straight web of paper upon a tapered man drel, so as to produce a plurality of super, imposed plies in conformity with the surface of the mandrel, and precluding a nonconformity in the winding of the web by effecting a longitudinal variation of a lateral portion of the web, through the introduction'thereinto of flat tapered plaits, thereby compensating for the taper ofthe mandrel.
